Ordered: Tegretol 150 mg po BID
Supplied: Tegretol 20 mg / tablet
1. How many tablets would you administer per dose?
2. How tablets would you administer per 24 hours?
1. 150/20 x 1
= 7.5 tablets per dose
2. 150mg/2 = x/24
=1,800 tablets ?
I am very confused on second question.
To calculate how many tablets you would administer per dose, you need to divide the ordered dose (150 mg) by the strength of each tablet (20 mg). This will give you the number of tablets required per dose.
So, for the first question:
Number of tablets per dose = 150 mg / 20 mg
= 7.5 tablets per dose
However, since you cannot administer half a tablet, you would round this down to the nearest whole number. Therefore, you would administer 7 tablets per dose.
For the second question, you want to calculate the total number of tablets administered in a 24-hour period. To do this, you need to multiply the number of tablets per dose by the number of doses taken in 24 hours.
The dosage frequency is "po BID," which means "by mouth twice a day." So, in 24 hours, you would have two doses.
Therefore, for the second question:
Number of tablets per 24 hours = Number of tablets per dose × Number of doses in 24 hours
= 7 tablets × 2 doses
= 14 tablets per 24 hours.
